Best ResponseYou've already chosen the best response.0The radius of a coneshaped tank is 4 feet less than its height. If the height of the tank is (x  3) feet, the expression below shows the volume of the tank: 1 over 3π(x  7)2 (x  3) What does the factor π (x  7)2 represent?

Best ResponseYou've already chosen the best response.1They want to know what pi*(x7)^2 represents... in other words now that you have r = x  7 the question is , what is pi*r^2

Best ResponseYou've already chosen the best response.1ok, the givens in the problem are, r = h 4 (radius is 4 less than height) h = x  3 (height is x  3

Best ResponseYou've already chosen the best response.1To combine those two, you can take the h = x  3, and insert that into the radius r = h  4 = (x3)  4 r = x  7 so the radius is in terms of X now, not the height

Best ResponseYou've already chosen the best response.1The radius is given in terms of the height of the cone... the height is given in terms of a measurememt X... is is one of those compound functions like.. r [ h(x)] You use the height value in the radius , to get r(x), the radius in terms of the measure X instead of height h
